Hierarchical Fair-Service Curve (HFSC) is a network scheduling algorithm designed to manage bandwidth allocation in a way that ensures fair and efficient service to different classes of traffic in a multi-level hierarchy. It was developed to overcome limitations found in earlier scheduling and traffic management techniques by combining aspects of both class-based queuing and traffic shaping.
